Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of posterior wall of acetabulum dissection armor plate.
Background technology
According to the typing of fracture of acetabulum, Acetabular posterior wall fracture proportion in all fracture of acetabulums is the highest, accounts for 1/4th left and right.Because Acetabular posterior wall fracture relates to hip joint face, and often merge femoral head backward dislocation, therefore, majority need to carry out operative treatment, in requiring articular surface anatomical reduction and giving enough, fix and obtained early functional training, avoid Hip instability and traumatic arthritis to form.
No matter the steel plate using at present or rebuild band, in the therapeutic process of fracture of acetabulum, due to acetabular bone and pelvis anatomical shape irregular, and very complicated, skeleton surrounding soft tissue size and geometric also limited size and the intensity of implant, after fracture, give operative reduction and interiorly fixedly brought very large difficulty and risk.At present common to be applied to the fixing internal fixation steel plate of Acetabular posterior wall fracture be reconstruction plate, applies above-mentioned reconstruction plate in art, needs temporarily mouldingly, causes operating time to extend; Art light plate is interim moulding to be surveyed and by hand, therefore the matching degree of its shape and skeleton local surfaces is not good enough, can not ensure the tight attaching of steel plate on skeleton with looking, and steel plate does not attach and will make the fracture having resetted produce displacement; And after existing broken bone is merely able to push down by steel plate, steel plate both sides are fixed, its stability deficiency, constant intensity is low, in the time that patient meets accident, can not effectively protect fracture site, causes state of an illness aggravation.
Utility model content
Technical problem to be solved in the utility model is, for above-mentioned the deficiencies in the prior art, to provide one to be easy to moulding, the posterior wall of acetabulum dissection armor plate of the high and good stability of constant intensity.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of posterior wall of acetabulum dissection armor plate, body is formed in one, body two ends are strip the first plate body laterally moving towards, the second plate body and the 3rd plate body that mid portion is horizontal trend, be set up in parallel, have a gap area between the second plate body and the 3rd plate body, and the width of described mid portion is greater than the width of two end portions; Two the first plate bodys) on be provided with sliding eye, the os integumentale screw for fixed body and pressure bone broken line is installed on sliding eye; On the second plate body and the 3rd plate body, be provided with lock hole, on lock hole, be provided with for the fixing bone piece of pulverizing and prevent the lock screw being shifted.
Further, the width of this first plate body is greater than the width of the second plate body, and the width of the first plate body is greater than the width of the 3rd plate body.
Further, this body is the concavo-convex anatomical shape that is applicable to human body posterior wall of acetabulum, and is titanium alloy material.
Further, this sliding eye is oval unthreaded hole, and its long axis direction is consistent with body trend.
Further, the sliding eye on this each first plate body is be arranged in order multiple.
Further, this os integumentale screw comprises screwed os integumentale screw bar and os integumentale screw cap.
Further, the interior hexagon that this os integumentale screw cap is outer smooth.
Further, this lock hole is for being with female circular hole.
Further, the whole lock holes on this second plate body and the 3rd plate body are common forms side by side or W type is arranged.
Further, this lock screw comprises lock screw bar and the locking screw head of a nail, and locking screw head of a nail outer wall has the external screw thread matching with the screw thread of lock hole, and described lock screw bar is the smooth shaft of front end tip.
The utlity model has following advantage:
1, the second plate body and the 3rd plate body are placed on the place of broken bone, and lock screw is installed in lock hole, have solved the only deficiency of the fixing broken bone of depended on pressure; The spiro rod length of lock screw is 4mm～20mm, and the diameter of lock screw bar is 2.5mm, does not only penetrate acetabular bone and affects joint motion with bone fixation piece guarantee through one deck cortex under steel plate, and lock screw bar front end is tip, has avoided penetrating acetabular bone.
2, on steel plate body, the quantity of lock hole and sliding eye can have different settings, makes steel plate be divided into large, medium and small three kinds of specifications, meets different patients' demand.
3, the width at steel plate two ends is greater than the width of the middle arbitrary plate body of steel plate, and the plate body in the middle of making is like this easy to moulding.
4, the sliding eye on steel plate body be shaped as ellipse, and its long axis direction is consistent with body trend.In the time that housing screw is installed, housing screw is put near the one end in steel plate body outside by sliding eye, in actual mechanical process, housing screw can slide along the direction of the major axis of sliding eye, plays the effect of inside pressurization; The other end adopts identical method to put into os integumentale screw, and pressurization in twocouese like this can make fracture line compress.
5, the whole lock holes on the second plate body and the 3rd plate body are common forms side by side or W type is arranged, and in use, the many plate body in hole is near acetabular bone outside.
6, this utility model can appropriate torsion, bending in three dimensions, be convenient to moulding so that better with skeleton laminating, bear joint motion and load.
7, steel plate is titanium alloy material, and itself and the tissue compatibility are good; Cell reaction is little; And be easy to mouldingly, make anatomical form.
